Abstract: The present invention relates to a method of marking a petroleum hydrocarbon by adding to and uniformly mixing with said petroleum hydrocarbon a chemical marker of general formula (I)




wherein two of the residues R1-R10 are independently of each other selected from C1-C4-alkoxy, and eight of the residues R1-R10 are independently of each other selected from the group consisting of hydrogen and C1-C4-alkyl, as well as to a composition of a petroleum hydrocarbon comprising a petroleum hydrocarbon and at least one chemical marker of general formula (I). The presence and concentration of the chemical marker of general formula (I) in the composition of the petroleum hydrocarbon can be advantageously determined by laser ionization coupled with mass spectrometry or by laser ionization coupled with ion mobility spectrometry.

Abstract: A method is disclosed for converting biomass into a fuel additive, the method comprising: liquefying the biomass to form a liquor; neutralizing the liquor; precipitating lignin out of the liquor; extracting furfural (FF) and 5-hydroxymethylfurfural (HMF) from the liquor; and hydrodeoxygenating (HDO) the extracted furfurals over a Cu—Ni/TiO2 catalyst. The catalyst for hydrodeoxygenating (HDO) furfural (FF) and 5-hydroxymethylfurfural (HMF) to methylated furans comprises copper-nickel (Cu—Ni) particles supported on titanium dioxide (TiO2), and wherein the copper-nickel particles form core-shell structures in which copper (Cu) is enriched at a surface of the catalyst.
